Buildozer command failed

[Güray Yildirim]

Hi,
I am trying to build an apk file via Buildozer. What I have done is:

- Installed buildozer from github source.
- put a running main.py in a folder.
- In the folder, run "buildozer init" => File buildozer.spec created, ready to customize!
- "buildozer android debug" gives me:
# Check configuration tokens
# Ensure build layout
# Check configuration tokens
# Preparing build
# Check requirements for android
# Install platform
# Apache ANT found at /home/guray/.buildozer/android/platform/apache-ant-1.8.4
# Android SDK found at /home/guray/.buildozer/android/platform/android-sdk-21
# Android NDK found at /home/guray/.buildozer/android/platform/android-ndk-r9c
# Android packages already installed.
# Check application requirements
# Compile platform
# Command failed: ./distribute.sh -m "kivy" -d "myapp"

What can I do for solving this?
Thanks.
